N2 - We present an iterative decoding algorithm for annihilating trapping sets in low-density parity-check codes. In addition to classic messages, subsets of variable nodes communicate directly. We show that by allowing variable nodes to collect information from a larger part of a graph, significant improvement can be achieved in the error-floor region, compared to the classic hard decision decoders. We also propose a new hybrid hard-decision decoding algorithm which employs described strategy and the Gallager B decoders as its components. Our decoder outperforms all known hard-decision decoders of same or higher complexity.
